Measuring mitochondrial respiration in frozen tissue samples provides the first comprehensive atlas of how aging affects mitochondrial function in mice.

Cells that have a high-energy demand such as nerve cells and muscle cells contain a large number of mitochondria to maximise ATP production by aerobic respiration. A muscle cell contains ...

Cellular respiration Cellular respiration refers to the breakdown of glucose and other respiratory substrates to make energy carrying molecules called ATP. Energy systems in muscle cells During ...

In the same way that the genetic code enables information to transcend chemistry, so Mitchell's proton gradients enable cellular ... respiration, which supplies more than 80 percent of our ATP.
